Abstract

In this paper, a fast configuration for Motion Estimation (ME) is described in order to reduce the computational time of the new High Efficient Video Coding (HEVC). This configuration uses the Coded Block Flag (CBF) Fast Method (CFM), the Early Coding Unit (CU) termination (ECU) and the Early Skip Detection (ESD) modes. The Diamond Pattern is used as a search algorithm for ME in the encoding process. Compared to the latest original reference software test model (HM) 16.2 of the HEVC, experimental results had showed that the complexity is reduced, in average, by 56.75% with a small bit-rate and PSNR degradation.

HEVC视频编码的快速运动估计

为了减少新的高效视频编码(HEVC)的计算时间，本文描述了一种快速的运动估计(ME)配置。该配置采用CBF (Coded Block Flag) Fast Method (CFM)、ECU (Early Coding Unit) termination (ECU)和ESD (Early Skip Detection)三种方式。在编码过程中，使用菱形模式作为ME的搜索算法。实验结果表明，与HEVC的最新原始参考软件测试模型(HM) 16.2相比，该算法的复杂度平均降低了56.75%，比特率和PSNR的下降幅度较小。
